Latest Patents

Florian Pfeiffer's latest patents include a method and security module for receiving two signals. This method involves producing an output bit stream for a first signal of a first carrier frequency. The security module receives an input signal that comprises both the first signal and a second signal of a second carrier frequency. A mixed signal is formed, which includes the first signal at the first carrier frequency, the second signal at the second carrier frequency, and a mixed product at an intermediate frequency. The mixed product is then demodulated by a second nonlinear component to output a second baseband signal. This process generates a second bit stream related to the first signal in the mixed product. The output logic is designed to produce the output bit stream for the first signal, selecting either the first bit stream or the second bit stream as the final output.

Another significant patent by Pfeiffer is a method and security module for the adaptation of a reference value for generating a bit stream. This method and circuit are arranged to adapt a first reference value for generating a first bit stream from an input signal by a first amplitude adapting unit. The input signal consists of both a first and a second signal, which together form a baseband sum signal. A first non-linear component demodulates the input signal, outputting a demodulated input signal. The amplitude adapting unit then generates the first bit stream based on the first reference value. A reference-value adapting unit includes a detection unit that identifies the first and second signals. When the first and second signals are discontinued, an adjusting unit modifies the first reference value to a basic reference value.
